CVE-2026-27754Network attack vector

Authentication bypass via weak MD5 session cookies

Published Feb 27, 2026 · Updated Feb 27, 2026

Weak session-token generation in SODOLA SL902-SWTGW124AS firmware through 200.1.20 allows remote attackers to gain unauthorized access. The web-management session-cookie generator applies MD5 to predictable token material, producing cookies that attackers can forge and the device accepts. No authentication or user interaction is required; a forged cookie grants access to the switch management interface, with reported confidentiality and integrity impact only.
